TopThe first humans, whose brains weighted 500 cc, populated the Earth about six million years ago; however, it was only 6,000 years ago they began to live as civilized people with much bigger brains of 1350 cc. During the last six millennia, humans developed about 26 natural civilizations (Toynbee, 1995) and two planned civilizations, the Soviet and Nazis (Targowski, 2009). We currently experience eight religion-oriented civilizations (Western, Eastern, Chinese, Japanese, Islamic, Hindu, Buddhist, and African) and one economy-oriented civilization, the newly emerging Global civilization. A concept of the emerging civilizations is shown in Figure 1.
